What would cause an SSC file to simply stop working?

[PlutonianEmpire]

That's exactly what just happened. No virus, no modification of code, no updates off the SVN, no changes *whatsoever*. And I tried cutting and pasting the code to an entirely new file, it still didn't work.

So I don't know what I did, but this laptop came extremely close to ceasing to exist when I discovered this.

Of course, it wouldn't have been the first time I made one of my computers cease to exist....

So.... Yeah.

I don't know what could be wrong with the code, as the Celestia code language for Notepad++ tells me everything's in tip-top shape, but maybe someone could take a look at it? Find something I missed?

I've tried everything I could think of, but instead of making the selected spacecraft invisible, nothing happens.

It's quite irritating, because this exact same code -- EXACT SAME CODE -- was working absolutely perfectly since I made it (the exception that the re-centering attempt never even worked for the spacecrafts since they had .xyz orbits) until tonight when it just stopped working.

The SSC for the rest of the system, and the above code, is in the attached zip.

Maybe you must specify the radius of the spacecrafts. The class is radius-sensitive.

[PlutonianEmpire]

Setting the CustomOrbit to "none" or adding radius definitions did not fix it.

Even adding in fake elliptical orbit definitions failed.

If you look at what I have done which worked previously, I set the classes to invisible for all the spacecraft as a result of being unable to recenter their orbits properly, and until this point, the SSC worked and they were completely invisible, as it should be doing. Somehow, they're not invisible anymore.

[PlutonianEmpire]

Ok, I don't know why I didn't think of it before, but I tried some re-ordering, and put all the spacecraft at the bottom, and the asteroids from the Motherlode started working properly, meaning they were now re-centered to the new Barycenter; but the spacecraft still didn't work. So I figured Cassini might have been the problem, so I moved the Voyager probes to the top of the spacecraft section, but no change, so I'm guessing there's something about the spacecrafts and/or their customorbits that are causing them to not re-center or disappear like they should be doing.

EDIT: I've been neglecting to mention my file structure for this. it is as follows:
C:\Users\<me>\Documents\Celestia\extras\Solar System\TemporaryExile2\zTwoSuns\Miscellaneous.ssc

For the voyager probes:
C:\Users\Eugene\Documents\Celestia\extras\Solar System\voyager-full\voyager.ssc

(Cassini, Huygens and Galileo still in their "extras-standard" directory)

And the asteroids:
C:\Users\Eugene\Documents\Celestia\extras\Solar System\<asteroidname>.ssc

And apparently, while looking up the structures, I found out that I deleted the "impactors" collection I got from the motherlode, so I deleted them from the SSC file, keeping all the rest, and moved comet lovejoy to below the spacecraft, and removing all definitions but the "class invisible" definition from the spacecrafts. That's when it got weird. Apparently, even though the spacecrafts failed to register any changes, comet lovejoy (itself being simply in the Solar System folder) still managed to re-center to the new barycenter.

Here's the code for Miscellaneous.ssc in it's new arrangement (getting the asteroids from the motherlode should be a piece of cake. ):
